[FREE] [Steam] Minion Masters - Invasion

They create a free dlc with each new expansion, the dlcs are useless in my point of view (since they are things that you can get fast in the game), I guess they are more interested in selling season passes than dlc (what I know dlc band is a bonus for them).

It is an interesting game and good for quick games, but it feels like a mobile game. "Clash royale 2.0"

Others will see "free DLC" and give it a try. It's also a way to pique the interest of old players who have drifted away from the game but might be interested to see what's new. But if it's always free, its perceived value goes down and less people will find it interesting. It's all a numbers game--the more people try it out, the more likely some of them will stick with it and buy premium in-game currency, which is where the devs make their money.

huh? They release a new DLC for free every so often. I have played the game for a while and very much enjoyed it. My pretty old computer didn't like it much though. There are a couple of DLCs that will never be free. Premium Upgrade, and All Masters Upgrade. They make their money on those. The rest of the DLCs are free for a short time after release. I have all of them. The free DLCs are just some in-game items. You could earn them through gameplay, but they give a nice boost for newer players especially.

I hate to break your bubble but I'm 99,9% sure they're only giving them for free at the start of a new expansion/new dlc.

So, unfortunately, I doubt you'll ever see the old ones for free :(
(I know the pain, I've missed one somewhere)
